Taylor Swift's best friend to wed

Taylor Swift is planning another big wedding - her best pal is engaged.

As the Love Story singer enjoys her new romance with actor Tom Hiddleston in Europe, her longtime BFF Abigail Anderson has announced her boyfriend, Matt Lucier, has proposed.

The bride-to-be shared the exciting news with followers and friends on Instagram on Tuesday (28Jun16).

Next to a photo of herself kissing her new fiance, she wrote: "Tonight I answered the easiest question I’ve ever been asked.

"Without any doubt and without fear - I am so excited for this next chapter in our lives... Thank you to my family & all of my friends that went the extra mile to make sure this night was everything I’ve ever imagined."

Matt reportedly proposed to Abigail at Centennial Park in their native Nashville, Tennessee.

She also posted a stunning lakeside shot of the couple, adding the caption: "@abigail_lauren lucier... Has a nice ring to it... Boom! pun of the day goes to me #dreamgirl."

Anderson was the inspiration behind Swift’s 2009 single Fifteen, which chronicles the story of the duo’s freshman year of high school.

Taylor even namechecked her pal in the song, writing: "You sit in class next to a redhead named Abigail and soon enough you’re best friends..."

And last year (Apr15), the pop star threw her pal a 25th birthday party in Nashville, where she surprised guests with a performance from Abigal's favourite band, Dashboard Confessional.

Abigail has been a good friend to Taylor throughout her many celebrity break-ups, and earlier this month (Jun16), she posted a sweet message to Swift after news broke she had split from boyfriend Calvin Harris.

"There are a few things more significant or valuable than a friendship that will withstand the test of time," she wrote on Instagram. "Thank you for getting me. Always. @taylorswift."
